The improvement is that the reciprocating motion of the movable mould 202 is utilized to generate a left-right inclined acting force on the adjusting plate 405, so that on one hand, the effect of orientation is achieved on the transmission of injection molding products, and on the other hand, the injection molding products on the surface of the clamping plate 404 are sequentially transmitted on the surface of the conveying belt 411, and the injection molding products are conveniently and sequentially guided onto the surface of the clamping plate 404.
In summary, the working principle of the scheme is that the movable mold 202 separates the movable mold 202 from the fixed mold 201 under the action of the tension force of the first hydraulic telescopic rod 206 and the screw rod 207, and the injection molding product inside the fixed mold 201 is clamped on the surface of the movable mold 202, when the surface of the engagement plate 306 is in engagement contact with the surface of the rotating gear 307, the rotating rod 301 and the sleeve plate 302 can rotate towards two sides of the surface of the movable mold 202, so that the clamping block 304 can clamp the surface of the injection molding product, and meanwhile, the clamping piece 305 can clamp the center position of the surface of the injection molding product and the waste generated by the gate, so that the subsequent recovery treatment is performed after the shearing of the waste by the shearing blade 311;
After the clamping block 304 and the clamping piece 305 clamp and clamp the injection molding product and the waste, the connecting plate 310, the clamping block 304 and the clamping piece 305 are arranged in parallel and correspond to each other, so that the shearing blade 311 can rotate and correspond to two sides of the waste clamped on the surface of the clamping piece 305, and as the cylinder 309 is arranged on one side of the back surface of the connecting plate 310, the electromagnetic valve is used for controlling the inlet and the outlet of compressed air, so that the piston rod of the air cylinder 309 moves, the piston rod is sleeved and arranged inside the connecting plate 310, and one end of the piston rod is connected with the shearing blade 311, therefore, the shearing blade 311 shears the sprue waste and is clamped inside the clamping piece 305, the sprue waste is prevented from falling into the collecting groove 406, and the sprue waste is convenient to collect and treat;
After the casting gate waste of the injection molding product clamped on the surface of the movable mold 202 is sheared off, the surface of the injection molding product movable mold 202 is separated by the pushing block 208, and at the moment, the lower surface of the movable mold 202 generates a pushing force from left to right on the upper surface of the adjusting plate 405, so that the lower surface of the adjusting plate 405 is inclined to the left side, and then the injection molding product is transmitted from the surface of the adjusting plate 405 to the surface of the clamping plate 404 arranged at the leftmost side of the upper surface of the conveying belt 411, otherwise, when the lower surface of the movable mold 202 generates a pushing force from right to left on the upper surface of the adjusting plate 405, the lower surface of the adjusting plate 405 is inclined to the right side, and meanwhile, the lifting rod 407 is lifted from left to right to be in contact with the surface of the driven rod 410, so that the driven rod 410 drives the linkage rod 409 to rotate to the right side, and then the conveying belt 411 is transmitted from left to right under the linkage action of the conveying belt 408, so that the leftmost clamping plate 404 moves to the right side, and the injection molding product is convenient to drop down through the adjusting plate 405, and when the clamping plate 404 on the upper surface of the conveying belt 411 is clamped with the injection molding product, the injection molding product is telescopic, and the second hydraulic expansion rod 402 arranged to move to the clamping plate 403 to the outer surface of the injection molding product.
